DANIEL B. HASELTON, OE CHARLESTON, SOUTH CAROLINA, AssIeNon' To THE SOUTHERN COTTON PICKING COMPANY, or SOUTH CAROLINA.v

COTTON-HARVESTER.

SPECIFICATION forming part of Letters Patent N o. 328,116, dated October 13, 1885.

Application filed November 2l), 1883. Serial No. 112,290. (No model.)

T o Aall whom it 71mg/ concern.-

Beit known that I, DANIEL B. HASELTON, a citizen of the United States, residing at Charleston, in the county of Charleston and State of South Carolina, have invented certain new and. useful Improvements in Gotton-Harvesters,l of which the following is a specification, referencebeing had therein to the accompanying drawings. p'

My invention has relation'to cotton-harvesters, and thev object of it is to simplify the construction .and facilitate the operation of the picking mechanism, whereby the plants are thoroughly searched and all of the ripe cotton removed, while the green or unopened bolls are not interfered with; and to these ends the novelty consists in the construction ofthe same, as will be hereinafter more fully described, and particularly pointed out in the claims.

In the accompanying drawings similar letters of reference indicate like parts of the in vention.

Figure l is a plan View of my improved picker. Fig. 2 is a transverse view, partly in section; Fig. 3, a cross-section of the stationary circular track; and Fig. 4 is a section through outer end of one of the .picker-cylinders enlarged, to show the spring in the cap. l lis a central shaft, and B a cast-iron hub having a seriesof radial arms, b, provided with Set-screws c, by means of which the shafts' C are adjustably secured in the holes in said arms. l

D is a sleeve, to the inner end of which is secured a disk, d, or sleeve, having an elastic ring, d", which forms a friction-pulley and serves to rotate the sleeve when said pulley is in contact with the track.

E isa cylinder secured tothe sleeve D so as to revolve with it, andthe periphery of the cylinder is provided with a series of teeth, the points of which are depressed below the surface, so they will engage the elastic or ripe cotton, while not the unripe bolls or twigs and the like.

The outer end of the cylinder E has a recess, e, and a cap, F, is secured thereto by means of the "screw G, 'and the inside of this cap has a spiral spring, H, the outer end of which is secured to said cap at h, and its inner .end'to a -ly in the opposite direction,

collar, I, provided with a square centralopeningto receive lthe square end c of the shaft C;

C by means of the disk d bearing on the track K when the central shaft A is revolving, the spring Hwill be wound up, and when the friction is removed between the disk d and track K,the spring throws the cylinder rapidand the.spring resumes its normal position. The circular track K is rigidly secured to the framework of the machine by means of the brackets la k, and L is a guard extendingV around the rail K, which prevents the disks d from slipping off, except at the point Z, where the guard is recessed to allow the picker-cylinders to be removed and replaced, as occasion requires.

N is a recess or depression in the face of the track, so that the' friction-disk d is clear of the track at that point.

In operation the shaft A is revolved, and as one of the frietiondisks d strikes theend not' the track K it begins rotating,which ofcourse rotates the picker-cylinders on the'radial shafts C, in addition to the motion imparted to them in their own plane bythe shaft A; and during this motion the teeth collect the ripe cotton and the cylinder winds up the spring H until the friction-disk cl arrives at the point a', which is the beginning of the depression N in the track K, when the friction and winding suddenly cease, the motion ofthe cylinder is reversed,'and the picked cotton removed from the teeth by its own rapid reversed motion, and it falls into any convenient receptacle in position to receive it. As the friction-disk passes across the depression N its revolution on 'its own axis is reversed with the cylinder, and does not begin to Wind again until it comes in contact with the end n, which is the beginning of the revolves, picks the cotton, spring, as before. 5

C a slight bend at the end of the arm b, and by adjusting said shaft in the arms by means of the set-screw, so that it will project up or down, `it Willliae': seenv that the sei'iesof cylinders track, when it. and winds up the` Y which aref mounted on the same hub will not travelin ICO.

` s In the cylinder E (shown 1n dotted llnes 1n l Fig. l) I have given the ,shaft out reference to the position of said shaft. Of

' as eiectively as before,

courseif the bend be a great one, the setscrew c would have to be loosened, the bent shaft removed, anda new one inserted; but Where the bend is only a slight one, which would simply throw the shaft out of its line or plane, the cylinders will revolve and operate as above set forth.

'In practice, the shaft A may be ol' any dey sired length, and a series of the hubs B .se-

cured thereto at suitable distances to accom plish .the best results;` and I have found that great advantage results when these central shafts are mounted in an inclined position with the shafts inclined forward,.so as to begin operation upon ,the top of the plant and work downward toward the base. L vHaving thus-fully described my invention, what I claim as new and useful, and desire to secure by Let-ters Patent of the United States, 1sv l'. ,The combination, with the rotating hubs B and stationary circular track K,of the shafts U, upon' which are mounted the sleeves I), having' friction-disks d d', and picking-cyiin ders E, as and for the purpose set forth.

2. The combination, with the hubs B, having radial shafts C, provided with sqnareheadsi c', of the collars I and sleeves D, having caps F, .provided with springs H, as and for the purpose set forth.

3. The hubs B, shafts C, sleeves D, springs 4o H, and friction-wheels d d', in combination with the circular track K, having recess N, as and for the purpose set forth.

4. The combination in a cotton-harvester of the sleeves D, provided with friction driv- 45 ing-wheels, and the pickencylindels mounted on said sleeves,as and for the purpose set forth. 5., The combination, with'thc rotating picker-cylinders E, having friction-driving wheels d, ot' the track ing recess l, as and for the purpose set forth.

6. The combination of the rotary shaft, the series of rotary picker cylinders mounted thereon,and means,substantially as described, for rapidly rotating verse direction at a higher rate of speed than in their forward rotations, whereby the gathered cotton `may be discharged by 'the said rapid rotation of the stems, as set forth.

7. In a cotton-harvester, the combination of 6o.

a rotary shaft, a series of picker-cylinders radially mounted thereon, means, substantially as described, Vfor rotating said cylinders on their own axes in one direction to gather the cotton, and means,substantially as described, 65

for consecutively rotating them at an acceleratcdspeed in the opposite direction to discharge the gathered cotton, as set forth.

In testimony whereof I 'atlix my signature in presence of two ,witnesses i DANIEL AB. HASELTON.
